I tried manually to install MIME-Lite beside through CPAN installation. but I am unable to install MIME-Lite-3.021 Meanwhile I had upgraded my koha-3 beta2 version to koha-3 latest. 2) When I checked in ABOUT KOHA==>perl module showing MIME::Lite module is missing And when I run this command perl -M'MIME::Lite' -e print showing can't find an executable sendmail at -e line 0 Compilation failed in require. BEGIN failed--compilation aborted. 3)I am able to add records through z3950 but I am unable to see latest added records. Old records are retrievable on OPAC 4)Now I am unable to get my OPAC.When I searched my record it retrieves. When I click on any record gives error..........
